Fallout 3 - Got all the achievements and DLC for it a long time ago, but recently started a new character. I did O:A, The Pitt, and the main questline of Point Lookout so far. My new character is a stealthy melee character that also specializes in repair and lockpick, but is terrible with computers (19 science skill :))
Assassin's Creed 2 - I finished Assassin's Creed 1 a while ago too (all achievements but 3 D: completionist, templars, and 50 combo attacks.) My cousin lent me this one a couple of days ago. Just got up to Venice and where you learn the jump and grab thing from the thieves. I hate the layout of Venice so much though, I am having trouble picking it up again.
Pokemon Blue - Restarted. Current team is Nidoking, Exeggcute (had to go to serebii to see how to spell that D: ), and Flareon. I'm at Fuchsia with 5 badges though, so i'm getting my next member (Starmie) soon.
Pokemon Heart Gold - EV training random pokemon. I'll be sitting here and think "Oh, I think i'd like a Snorlax." and i'll breed one for natures/IVs and EV train it for fun. Post-game Heart Gold is SO BORING.
